Documentation on this action change is very very sparse.

Any pointers to examples or use cases would be helpful.

I've tried using it and got quite a few errors that look like:

ERROR [org.nuxeo.ecm.platform.task.providers.UserTaskPageProvider]org.nuxeo.ecm.core.api. ClientException: Failed to get document cbbb1b48-55ab-4f52-85df-39416b68d0f5

in log nuxeo log file.

Thanks,

Karl
